What the study statuses mean

This study's is highlighted.

Recruitment status, easiest to join first

Recruiting now
This trial is taking on new participants right now.
Not yet recruiting
Registered, but not yet taking participants.
By invitation only
Not open to general applications. Only people the study team invites can take part.
Paused
Paused for now. It may or may not start again.
Ongoing This study
Running, but no longer taking on new participants.
Completed
The trial has finished. Results may not be published yet.
Stopped early
Stopped early, before it reached the end. That can be for many reasons, including safety.
Cancelled
Cancelled before anyone took part.

Expanded access (not trials)

Expanded access
Not a trial. This treatment can be requested outside a study, case by case, for people who qualify.
Expanded access (paused)
Not a trial. The treatment can normally be requested outside a study, but is unavailable right now.
Expanded access (ended)
Not a trial. The treatment could once be requested outside a study, but no longer can.
Approved
The treatment has been approved, so it is available normally rather than through this programme.

When the status isn't known

Details not published
The full record has not been published yet, so there is little to show here.

Summary

This Phase II trial is studying whether proton beam therapy, with or without standard photon radiation, can effectively treat skull base chordoma, a rare tumor at the base of the skull. Nineteen participants who had surgery to remove as much tumor as possible are receiving daily radiation treatments for 35-39 sessions. Researchers are tracking how long it takes for the tumor to come back and how safe the treatment is.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
Proton beam therapy (a type of radiation)
What this could lead to
If successful, this could show that proton beam therapy is an effective way to control skull base chordoma and delay or prevent tumor regrowth after surgery.
What could go wrong
This is a small, early-phase trial with only 19 participants, so results may not apply to everyone. The study is no longer recruiting, and it is not yet known if proton therapy is better than standard radiation.
